CROSS-REFERENCE TO RELATED APPLICATIONS

This application a continuation of U.S. patent application Ser. No. 12/845,534, filed Jul. 28, 2010, which is based upon and claims the benefit of priority from Japanese Patent Application No. 2009-267336, filed Nov. 25, 2009, the entire contents of each of which are incorporated herein by reference.

FIELD

Embodiments described herein relate generally to an electronic device.

BACKGROUND

For example, Japanese examined utility model application publication No. H6-17345 discloses a conventional electronic device having a housing in which an interface component such as a connector is attached to face a through hole (opening) formed in the side wall of the housing. The connector is supported between a pair of supporting members (locking claws) provided on the bottom wall of the housing.

Besides, there have been known electronic devices, such as notebook personal computers and personal digital assistants (PDAs), having a flat housing in which a component retainer such as a battery retainer is formed in such a manner as to partly cut out the side wall of the housing. A component such as a battery is removably attached to the component retainer. The component retainer is spatially separated from the inside of the housing by a partition.

In an electronic device having a housing in which a component retainer is formed in the side wall of the housing as described above, a component is held in the component retainer. Therefore, an interface component cannot be provided. This is likely to limit the layout of the interface component in a region along the side wall in which the component retainer is formed.

Besides, in the conventional electronic device in which the interface component is supported between the supporting members, it is required to secure a space for the supporting members. Accordingly, the interface component cannot be arranged close (adjacent) to a component retainer by the space for the supporting members in a region along the side wall in which the component retainer is formed. This also is likely to limit the layout of the interface component.

The second protrusion extends from the second side wall and supports the connector at a position different from a position supported by the second side wall.

In the following embodiments, like components will be used with common reference numerals, and the same description will not be repeated.

With reference to FIGS. 1 to 6, a description will be given of an electronic device 1 according to a first embodiment.

As illustrated in FIG. 1, the electronic device 1 of the first embodiment is, for example, a notebook personal computer. The electronic device 1 comprises a flat rectangular first body 2 and a flat rectangular second body 3. The first body 2 and the second body 3 are connected by a hinge mechanism 4 to be relatively rotatable about a rotation axis Ax between a closed position and an open position (not illustrated).

The first body 2 comprises a housing 2 a that houses a circuit board, a hard disk, a cooling fan, and the like. The circuit board is mounted with a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and other electronic components (all not illustrated). The first body 2 is provided with a keyboard (not illustrated) as an input device configured to be exposed on a front surface 2 b. On the other hand, the second body 3 is provided with a display device (not illustrated) such as a liquid crystal display (LCD) panel configured to be exposed on a front surface 3 a. When the first body 2 and the second body 3 are in the open position, the keyboard and the display device are exposed to allow the user to use them. The housing 2 a is made of, for example, synthetic resin, metal, or the like.

The housing 2 a is relatively thin and flat, and has a side wall 2 c that spatially separates the inside of the housing 2 a from the outside. In the first embodiment, the side wall 2 c stands on a flat plate-like rectangular bottom wall 2 d.

A component retainer 5 is formed in the housing 2 a by cutting out a portion of the housing 2 a in a rectangular shape. In the first embodiment, the component retainer 5 serves as a battery retainer. That is, a battery as a component 6 is removably placed on the component retainer 5. The component 6 is formed into a rectangular parallelepiped to fit in the component retainer 5. As illustrated in FIG. 1, in the state where the component 6 is held in the component retainer 5, the surface of the side wall 2 c of the housing 2 a and a side 6 a of the component 6 are substantially flat. Similarly, the bottom wall 2 d (bottom surface) of the housing 2 a and a bottom 6 b of the component 6 are substantially flat.

A through opening 2 e is formed in the side wall 2 c where the component retainer 5 is formed. An interface component 7 such as a connector is attached inside the housing 2 a to face the through opening 2 e. The through opening 2 e may be formed as a through hole in the side wall 2 c. If the housing 2 a is formed of a combination of a first part 8 and a second part 9 as illustrated in FIG. 1, the through opening 2 e may be formed as a cutout at a boundary between the parts 8 and 9. In the first embodiment, the interface component 7 closest to the component retainer 5 is described as a connector into which an alternating current (AC) adapter cord pin is inserted. However, this is by way of example only, and the interface component 7 may be a local area network (LAN) cable connector, a universal serial bus (USB) connector, a female connector into which a connector pin of a head phone or a microphone is inserted, or the like.

In the above configuration, as illustrated in FIG. 1, the component retainer 5 (and the component 6 held in the component retainer 5) and the interface component 7 facing the through opening 2 e are arranged side by side in a direction along the side wall 2 c (in the first embodiment, the side wall 2 c closest to the rotation axis Ax of the hinge mechanism 4 and along the rotation axis Ax).

In the following, a description will be given of the attachment structure of the interface component 7 closest to the component retainer 5. As illustrated in FIGS. 2 and 3, the housing 2 a comprises the flat plate-like bottom wall 2 d, the side wall 2 c, and a partition wall 2 f. The side wall 2 c stands vertically (in the thickness direction of the housing 2 a) on the bottom wall 2 d and spatially separates the inside Is of the housing 2 a from the outside Os. The partition wall 2 f stands vertically on the bottom wall 2 d and spatially separates the inside Is of the housing 2 a from the component retainer 5. The side wall 2 c and the partition wall 2 f are coupled perpendicularly to form a corner 2 g.

As illustrated in FIGS. 2 and 3, a wall-like protrusion 11 is provided on the bottom wall 2 d at a position different from the partition wall 2 f. More specifically, the protrusion 11 is provided spaced apart from the partition wall 2 f in parallel with the partition wall 2 f. The interface component 7 is held between the partition wall 2 f and the protrusion 11. With this, according to the first embodiment, the interface component 7 can be attached close to the corner 2 g. In the first embodiment, the partition wall 2 f and the protrusion 11 position the interface component 7 in the horizontal direction of FIG. 2, and also restrict the horizontal movement of the interface component 7.

As illustrated in FIGS. 2 and 4, the interface component 7 comprises a rectangular parallelepiped main body 7 a, a first flange 7 b, and a second flange 7 c. The first flange 7 b faces or is in contact with the inner surface of the side wall 2 c. The second flange 7 c is provided spaced apart from the first flange 7 b in parallel with the first flange 7 b. The interface component 7 further comprises a harness pull-out portion 7 d on the opposite side of the first flange 7 b with respect to the main body 7 a. The harness pull-out portion 7 d is provided to lay out a harness 16 to the inside Is of the housing 2 a. As illustrated in FIG. 2, when the interface component 7 is attached, the harness pull-out portion 7 d is located close to the protrusion 11.

As illustrated in FIGS. 2 and 3, the partition wall 2 f and the protrusion 11 are provided with projections 2 h and 11 a between the first flange 7 b and the second flange 7 c. in the first embodiment, the projections 2 h and 11 a position the interface component 7 in the vertical direction of FIG. 2, and also restrict the vertical movement of the interface component 7. If an external force is applied to the interface component 7 from a component inserted through the through opening 2 e or the like from the outside Os of the side wall 2 c to the inside Is, the projections 2 h and 11 a prevent the interface component 7 from being pushed toward the inside Is. When attached in the housing 2 a, the interface component 7 does not need to be in contact with all the projections 2 h and 11 a, the partition wall 2 f, and the protrusion 11. The interface component 7 can be arranged to allow some variations due to production tolerance.

The housing 2 a of the first embodiment comprises the first part 8 and the second part 9 (see FIG. 1). The first part 8 comprises the bottom wall 2 d, the side wall 2 c, the partition wall 2 f, the protrusion 11, and the like illustrated in FIGS. 2 and 3. The second part 9 is coupled with the first part 8 to cover the opening (not illustrated) of the first part 8 on the upper side in FIG. 1. The first part 8 is located below the second part 9 in FIG. 1. The first part 8 and the second part 9 are coupled with each other by a coupling member (not illustrated) such as a screw. In the first embodiment, as illustrated in FIGS. 2 and 3, the first part 8 is provided with a boss 12 into which a coupling member such as a screw is threaded. More specifically, the boss 12 is formed in the shape of a column extending vertically on the bottom wall 2 d. In the first embodiment, the boss 12 is located close to the partition wall 2 f compared to the protrusion 11, and is integrated with the partition wall 2 f. Besides, as illustrated in FIG. 2, the boss 12 is located on the opposite side of the side wall 2 c with respect to the interface component 7. The boss 12 has a bottomed circular hole 12 a as an opening formed on the first part 8 side. If the coupling member is a screw, the bottomed circular hole 12 a serves as a female screw.

As illustrated in FIGS. 2 and 3, at the end 2 i of the partition wall 2 f and the side wall 2 c, a projecting wall 2 j is formed along the periphery of the inside Is. The engagement of the projecting wall 2 j and a groove (not illustrated) of the second part 9 suppresses the displacement of the first part 8 and the second part 9.

As illustrated in FIGS. 2, 3, and 5, in the first embodiment, the partition wall 2 f is provided with a recessed wall 2 k that is recessed toward the inside Is of the housing 2 a. As illustrated in FIG. 5, the recessed wall 2 k extends from the end 2 i of the partition wall 2 f to the bottom wall 2 d with substantially a constant width in the thickness direction of the housing 2 a (the vertical direction of FIG. 5). The shape of the recessed wall 2 k increases the rigidity of the partition wall 2 f.

As illustrated in FIG. 5, the recessed wall 2 k protrudes above the end 2 i. In the first embodiment, the portion protruding from the end 2 i is an engaging portion 13 a of an engaging mechanism 13. The engaging portion 13 a includes part of the recessed portion of the recessed wall 2 k as an engaging recessed portion 13 b. With the engaging recessed portion 13 b engaged with a claw or a protrusion (not illustrated) formed as an engaging portion on the second part 9, the first part 8 and the second part 9 are engaged with each other.

In the first embodiment, as illustrated in FIG. 2, since the interface component 7 is located close to the corner 2 g, the boss 12 is a little apart from the corner 2 g. Accordingly, the first part 8 and the second part 9 are likely to separate from each other on the side closer to the corner 2 g than the boss 12. In view of this, according to the first embodiment, the engaging mechanism 13 is provided closer to the corner 2 g than the boss 12 to prevent the separation of the first part 8 and the second part 9. Incidentally, the engaging recessed portion 13 b (the engaging portion 13 a) that constitutes the engaging mechanism 13 may be provided to the side wall 2 c. In this case, however, it is necessary to avoid interference with the interface component 7, and it is difficult to form a recessed portion as with the recessed wall 2 k formed in the partition wall 2 f. Therefore, the engaging recessed portion 13 b (the engaging portion 13 a) with higher rigidity is provided more preferably to the partition wall 2 f than the side wall 2 c.

In the first embodiment, as illustrated in FIG. 5, a guide rib 14 is formed on an outer surface 2 m of the partition wall 2 f on the outside Os of the housing 2 a. The guide rib 14 extends from the opening of the cutout of the component retainer 5 (the left side of FIG. 5) to the back side (the right side of FIG. 5) in parallel to the bottom wall 2 d. The guide rib 14 slidably guides the component 6 held in the component retainer 5. On a side of the component 6 is formed a groove (not illustrated) in which the guide rib 14 is fitted. The guide rib 14 extends across the recessed portion of the recessed wall 2 k. That is, the guide rib 14 prevents the opening of the recessed portion of the recessed wall 2 k from expanding. This further increase the rigidity of the partition wall 2 f.

In the first embodiment, as illustrated in FIG. 3, the bottom wall 2 d is provided with a second recessed wall 2 n for housing a different functional component than the interface component 7. In the first embodiment, the second recessed wall 2 n is a portion of the bottom wall 2 d that is recessed toward the inside Is of the housing 2 a. As illustrated in FIGS. 5 and 6, the second recessed wall 2 n provides a groove 2 o extending along a direction perpendicular to the partition wall 2 f. The groove 2 o holds a lock slider 15 that locks the component 6 held in the component retainer 5. As illustrated in FIG. 6, the second recessed wall 2 n supports the lock slider 15 in the groove 2 o such that the lock slider 15 is slidable between a lock position P1 and an unlock position P2. The lock slider 15 enters in the component retainer 5 in the lock position P1, while the lock slider 15 is retracted therefrom in the unlock position P2. More specifically, as illustrated in FIG. 3, an elongated through hole 2 p is formed in the second recessed wall 2 n. The through hole 2 p extends in a direction perpendicular to the partition wall 2 f. A claw 15 b of the lock slider 15 passing through the through hole 2 p from the groove 2 o side to the inside Is of the housing 2 a is engaged with the edge of the through hole 2 p. The lock slider 15 comprises a elongated rectangular parallelepiped main body 15 a, which is held in the groove 2 o having a substantially rectangular cross section formed by the second recessed wall 2 n as illustrated in FIGS. 5 and 6. As illustrated in FIGS. 5 and 6, a operation portion 15 c of the main body 15 a is exposed in the bottom wall 2 d side. Thus, the user can operate the operation portion 15 c to slide the lock slider 15 between the lock position P1 and the unlock position P2.

As illustrated in FIG. 2, the second recessed wall 2 n is located such that it overlaps part of the interface component 7 (the harness pull-out portion 7 d). Thus, the shape of the second recessed wall 2 n increases the rigidity of part of the housing 2 a that supports the interface component 7. In the first embodiment, as illustrated in FIG. 3, the second recessed wall 2 n is connected to the partition wall 2 f as well as the protrusion 11. In other words, the bottom wall 2 d, the partition wall 2 f, and the protrusion 11 are connected to one another by the second recessed wall 2 n. This effectively increases the rigidity of part of the housing 2 a close to the corner 2 g.

As described above, according to the first embodiment, the interface component 7 is held between the partition wall 2 f and the protrusion 11. Therefore, there is no need to provide a support member such as an engagement claw between the interface component 7 and the partition wall 2 f as disclosed in Japanese examined utility model application publication No. H6-17345. Accordingly, the interface component 7 can be located further close to the component retainer 5. Thus, components such as the interface component 7 can be efficiently arranged in the region along the side wall 2 c adjacent to the component retainer 5 in the housing 2 a.

According to the first embodiment, the boss 12 is located closer to the partition wall 2 f than the protrusion 11. Further, the boss 12 is located on the opposite side of the side wall 2 c with respect to the interface component 7. With this, in the structure in which the interface component 7 is located close to the corner 2 g, the boss 12 can be located further close to the corner 2 g. Thus, it is possible to prevent the separation of the first part 8 and the second part 9, especially of regions close to the corner 2 g.

According to the first embodiment, the engaging mechanism 13 is provided closer to the corner 2 g than the boss 12 to engage the first part 8 and the second part 9. Thus, it is possible to prevent the separation of the first part 8 and the second part 9, especially of regions close to the corner 2 g.

According to the first embodiment, the engaging portion 13 a that constitutes the engaging mechanism 13 is formed in the partition wall 2 f. It is easier to provide the engaging portion 13 a to the partition wall 2 f than to the side wall 2 c and also to secure the rigidity of the engaging portion 13 a.

According to the first embodiment, the partition wall 2 f is provided with the recessed wall 2 k that is recessed toward the inside Is of the housing 2 a. At least part of the recessed wall 2 k forms the engaging recessed portion 13 b as the engaging portion 13 a. That is, it is possible to increase the rigidity of the partition wall 2 f and the engaging portion 13 a by the recessed wall 2 k as well as to achieve the relatively simple structure of the engaging portion 13 a by at least part of the recessed wall 2 k.

According to the first embodiment, the guide rib 14 that slidably guides the component 6 held in the component retainer 5 is formed on the outer surface 2 m of the partition wall 2 f on the component retainer 5 side such that it extends across the recessed wall 2 k. The guide rib 14 further increase the rigidity of the partition wall 2 f.

According to the first embodiment, the boss 12 is integrated with the partition wall 2 f. Compared to the case where the boss 12 is provided separately from the partition wall 2 f, it is possible to increase the rigidity of the housing 2 a around the corner 2 g.

According to the first embodiment, the harness 16 is pulled out to the inside Is of the housing 2 a from a position closer to the protrusion 11 than the partition wall 2 f. This prevents interference between the harness 16 and the boss 12 located close the partition wall 2 f.

According to the first embodiment, the second recessed wall 2 n is provided at a position overlapping part of the interface component 7 (the harness pull-out portion 7 d in the first embodiment) in a direction perpendicular to the bottom wall 2 d and is recessed toward the inside Is of the housing 2 a. The second recessed wall 2 n houses the lock slider 15 as a different functional component than the interface component 7. This further increases the rigidity of the housing 2 a around the corner 2 g.

With reference to FIG. 7, a description will be given of a first body 2A of the electronic device 1 according to a second embodiment. In the second embodiment, as illustrated in FIG. 7, the interface component 7 is held between the side wall 2 c and a boss 12A. With this, the boss 12A can be used to position the interface component 7 and also restrict the movement of the interface component 7. Moreover, the boss 12A can be located further close to the corner 2 g compared to the first embodiment, which further increases the rigidity of the housing 2 a around the corner 2 g. Incidentally, the side wall 2 c corresponds to a first side wall, while the partition wall 2 f corresponds to a second side wall. Besides, the through opening 2 e corresponds to an opening, the component 6 corresponds to a module, and the interface component 7 corresponds to a connector. The boss 12A corresponds to a second protrusion. In the second embodiment, the interface component 7 is supported by the side wall 2 c, the partition wall 2 f, a protrusion 11A, the boss 12A, and the like.

In the second embodiment, the protrusion 11A is formed as a plurality of columnar protrusions. As in the first embodiment, the interface component 7 is held between the partition wall 2 f and the protrusion 11A. Otherwise, the second embodiment is basically similar to the first embodiment, and can achieve the same effect as described in the first embodiment.

The above embodiments are susceptible to various modifications and alternative forms. For example, the side wall, the partition wall, the protrusion, and the like can be provided to the top wall. Further, if the component retainer is formed into a recess, the embodiments can be applied to a partition wall between the component retainer and the inside of the housing. The interface component, the second recessed wall, and the like each can be in a different form and located in a different position. Besides, a different functional component than the lock slider can be employed.
